The code changes in `aviation_parser_test.go` update the ARR body parsing logic. The `ParseHeader` function now correctly handles ARR bodies with optional time components. This ensures accurate parsing of ARR bodies and improves the overall functionality of the aviation parser.
The code changes in `config.go` update the regular expression pattern for parsing ARR bodies. The previous pattern did not account for the optional time component in the body. The updated pattern now correctly captures the category, number, SSR, departure, arrival, and time components of the ARR body. This refactor ensures accurate parsing of ARR bodies and improves the overall functionality of the aviation parser.
